This invention relates to a roaster. for pimentos or the like, wherein the substance under treatment is exposed directly. to the open flame of the heating medium. In the preparation of pimentos for sumption, it is desirable to remove the outer peel. One method'hereto'fore employed comprises first softening the peel, usuallyby immersing the fruit in hot 011 orcaust c solul0 tion and then peeling it manually, wh ch is a tedious process. Roasters have also been used wherein the skin of the fruit was scare and afterward removed."

It is a primary object of to provide a roaster wherein the peel of pimentos or the like is burnt to a crisp or carbonized,so that it may be readily re moved from the fruit by subjecting it. to the water. It is a further object of this invention to provide a roaster in whicli'the fruit is given a continual turning movementwhile exposed to the flame, thus ensuring an even burning of the peel over the entire surface of the fruit and preventing damage by scorching the .pulp'in s ots. In ad 'tion; to the broader objects 0 details. of construction whereby a simple,

durable and economical structure is attained. v These objects are obtained by means of the embodiment of my invention illustrated v rivets 23, the sides of the hnks 21 serving in the accompanying drawing in which:

Fig. l is an elevation of a roaster'constructed in accordance with my invention; Fig. 2 isa cross section of the roasteron an enlar ed scale as seen on line 2- 20f Fig.1; ig. 3 is a fragmentary longitudinal section on an enlarged scaleas seen on 3--3of Fig. 2 showing 7 tier chain, and Fig. 1S-8 C10SS-SeCt10n O one of the carrier chains, as seen on line .4r-42 of Fig. 3. v 7

Referring moreparticularlyto the drawing, the roaster comprises ,a tunnel-like oven sisting material, supported and tied together with a suitable iron frame work' 8. The oven is o n at the ends and is provided with a series of openings 9 in its sides, those on one side being instag ered relation to those on the other. 'Exten mg longitudinally along each side of the oven and suprted on suitablebrackets secured to the pipes 10 to which are human conat the opposite end of the oven,

this invention v this invention, there are certain one end. Supported on the floor of lmedetailsof the car f through'them.

structure -7 of fire brick or similar heat re-' 1 lips move the the oven where it is exposed to the flame is connected burners 1 1 p'rojectin inwardly through the 0 nings in the si e walls of the oven. .A c. imney 12 is mounted on the oven roof to carry off the products of combustion. Mounted in bearings on one end ,of the frame work 8 is a shaft carrying a air of sprocket wheels 14 and arranged to e driven by a countershaft 15. A shaft and similar sprocket wheels 16 are supported adjustment means to move the shaft in a horizontal did' rection and take the slack out of the chain being provided. A pair of chains 17 and 18 are mounted on these sprockets, the upper reach of the chains moving through the oven, and the lower reach bein carried beneath it on suitable idlers 19. etween the chains within the oven is parapet wall or curb 20, of the same material as the oven, having a'rounded top for a purpose later described. V

As the chains are identical, only one will be described. I It consists of a number of links 21 pivotally secured-together, each link having outstanding arms 22 on either side, to which 'is secured, as b rivets 23, a semi-circular shell 24 preferaly of sheet metal and having an upstanding Ii 25 at e oven and secured together in egiaoedrelationship are 'p'pes-26 and 27. hese' sup ort the chain which slides thereon on the: eads of to hold it in place'laterally. The wear incident to the sliding of the chain through the oven on the pipes is taken by these rivets,

which may be easily replaced when necessary. These pipes are provided with suitable connections, not shown,

whereby a up culation of water may be maintained The operation ofthe roaster is as follows: The gas from the burners having been i nited 11nd the chains beingin motion, t e.-,

fruit which it, is desired to roast is fed to' the chain at the end of the roaster in a sufliciently small quantity so that it will form only a single layer thereon with some space between the individual ieces. These lie on the shells 24 of one or the other chains and partly on the wall 20, as clearly shown in Fig. 2. -As the chains advance, the fruit. along with them into partly fruit, being 11 suing from the burners 11. The

. able means.

or turned in various directions as it advances,

thus continually exposing fresh parts of the surface to the action of the flame; This insures complete and uniform carbonization of the peel over the entire surface of the fruit and prevents scorching of the fruit in spots.'

The fruit after being conveyed through the oven is discharged at the opposite end from that which it entered, where it may be removed from the chains by hand or other suit- It is then ready for further treatment. v v It is obvious that the portion of the chains within the oven will be subjected to the flame and liable to damage as a result. Accordingly I have provided means for cooling them. The chains slide through the furnace on pipes, forming rails as before describcd, which are kept cool by' circulating water through them.- As the chains arein contact with the pipes a portion of the heat absorbed through prising an oven,

by the formerwill be conducted away by the latter, which results in keeping the temperature of the chains below the point at which damage might occur.

What I claim is: I

1. A device of the character described comprising an oven, a conveyor havin a flight therein for causin fruit or the like to be transported theret rough, and stationary means in said oven for. acting upon said fruit to cause the latter to roll during its passage through the oven.

2. A device of the character described comprising a tunnel like oven, having a flight therein for transporting fruit orthe like therethrough and a curb in said oven extending alongside of said flight for engaging the fruit and causing the latter to be rolled during its passage" through the 3.,-A device of the character described ing therethrough, an endless conveyordisposed alongside of said curb whereby fruit may; rest on said conveyoriand against said curb and be rolled while being transported therethrough.

4. A device of the character described comburners directing flame into said oven through the sides thereof, a parapet wall extending longitudinally of said oven, a pair of chains arrangedto be moved saidw oven, one chain being disposed on either side of said wall, and guide means in said oven for said chains, said guide means being adapted to be maintained at a temperature below that of said oven.

5. A device of the character. described including an oven, there being openings in the 1 sides thereof, burners directing flame into said oven through said openings, a parapet wall with a rounded top intermediate the sides and extending longitudinally of said oven, a pair of carrier chains disposed in said oven, oneof said chains on each side of said wall, said chains being adapted to be moved through said oven in unison, guides in said oven for said chains and means to maintain said guides at a temperature below that of said oven. 1

6. A device of the character described including an oven, heating means for said oven, a parapet wall with a rounded top ex tending longitudinallyof said oven, a carrier disposed at the side of said wall and arranged to be moved through said oven, said carrier having a rounded upper surface, the rounded surface being on substantially the same level as the top of said wall whereby substantially spheroidal fruit may be supported by said wall and said carrier.

7. A device of the character described including an oven, heating means for said oven,

a parapet wall with a roundedtopextending,

longitudinally of said oven, a carrier. disposed at each side of said wall and arranged to be moved through said oven, said carriers having rounded upper surfaces the rounded surfaces beingon substantially the same level v as the top of said wall whereby substan tially spheroidal fruit may be supported uby said wall.

8. The combination of a conveyor having a flight for transporting fruit or the like, and v a curb extending along the side of said flight v for engaging the fruit and causethe latter to be rolled during itstransit. 1 e

9. The combination of a longitudinally extending parapet wall with a rounded-top, a carrier disposed atthe sides of saidwall, said carrier having a rounded upper surface, the rounded surface being on substantially the same level as the top of said wall whereby substantially spheroidal fruit may be sup-- ported by said wall and said carrier and rolled during its transit;
